Abstract: A set of carpal tunnel syndrome relief devices is provided for treatment of a subject. The set includes several devices configured to be applied to a wrist which may have various shapes and sizes. Each device may be configured for an adhesive application to a skin area on a proximal side of a wrist over a median nerve of the subject. One device may be selected to match the profile of the skin of the subject and provide a distance from the peak of the middle portion to the underlying skin of about 3 to 6 mm—so as to achieve optimal pull of the skin above the median nerve and relief of carpal tunnel syndrome. An alternative, subject-specific design of the carpal tunnel syndrome relief device profile is also described.

Abstract: A novel pillow is provided to easily adjust its height by pulling a lever on the side of the pillow to activate the air control valve configured to personalize the head support needed for that individual. Pulling the lever to a fully open position creates a larger air passage to the inflatable bladder and activates an air pump for rapid inflation of the pillow so as to increase its height. With a user head laying over the pillow, pulling a lever slightly opens up a smaller opening suitable for gradual deflation of the pillow and reducing its height caused by the pressure generated by the head. Soft comfort portion on top of the pillow enclosed in a stretchable fabric reduces surface tension and creates a softer feeling for the user thereby improving comfort and consequently sleep quality. An altimeter may be incorporated with the bladder to easily monitor sleep patterns of the user.

Abstract: A novel pillow is provided to easily adjust its height by pulling one or both levers of a unique double-lever air valve. Pulling a first lever opens up a smaller opening suitable for gradual deflation of the pillow and reducing its height under a pressure of a user head laying over the pillow. Pulling both levers together activates an electrically driven air pump to rapidly inflate the pillow through a larger opening so as to increase its height.

Abstract: A device (100, 200, 300) for identifying an arterial location includes a housing (110, 210, 310) with a tactile pressure sensor array (150, 250, 350) configured to detect pulsations of an artery once positioned over the presumed location of an artery. One of several LED lights (132, 232, 332) is energized to guide a clinician towards a preferred location of needle 10 insertion. The method of the invention comprises steps of positioning the device over the artery, reading pressure signals from individual pressure sensors, identifying peaks of pulsations and selecting the individual pressure sensor with the highest pulsation peaks as the closest to the artery located underneath. A corresponding LED light (132, 232, 332) is then activated to facilitate percutaneous access to the artery.

Abstract: A capacitive tactile sensor for measuring location and force of touch from an external object includes a drive electrode layer separated from a sense electrode layer by a dielectric substrate, which may be a two-sided FPCB. A first deformable conductive shield layer is further provided and is separated from either the drive electrode layer or the sense electrode layer by a first compressible dielectric layer. A control electronics are operatively connected to all of the drive electrode layer, sense electrode layer, and the first conductive shield layer. The control electronics may be configured to measure a change in capacitance upon the external object imparting local mechanical compression onto the first conductive shield layer and the first compressible dielectric layer. The tactile sensor improves reliability of interconnections between drive and sense electrodes and the control electronics.

Abstract: A force sensing touch screen input device is a solid assembly of multiple layers including a display with a touch-sensitive external surface, a first and second electrode layers separated by a compressible dielectric structure—forming a capacitive force-sensing array, and a rigid planar substrate. One or both electrode layers may be formed by metallizing a polymer surface of the rigid substrate or by creating a conductive electrode onto an internal surface of the display. To increase reliability, each layer is permanently adhered to or formed onto an adjacent layer over its entire surface, whereby preventing internal shifts therebetween. To increase response time, the cover glass flexibility, compressible dielectric structure and the gasket structure between the cover glass and the rigid planar substrates are selected to provide elastic compression and recovery during normal operating conditions.

Abstract: Apparatuses, devices, and methods for measuring pressure are described herein. In some embodiments, a device includes an insole configured to be disposed under a foot of a user during use. The device further includes a fluid reservoir formed at least partly within the insole, the fluid reservoir containing a fluid. The device further includes a sensor fluidically coupled to the fluid reservoir and configured to sense an indication of pressure in the fluid reservoir during use. The device also includes a communications component communicatively coupled to the sensor and configured to receive the indication of pressure from the sensor. The communication component is further configured to transmit pressure information associated with the indication of pressure to a remote device.

Abstract: A pressure sensor and pressure-sensing catheter in which a deformable pressure sensing membrane is separated from an inner metalized surface on a rigid support by an air gap. An input allows a voltage to be applied to an electrode on the sensing membrane and an output allows reading of the signal modulation from the support surface. An outer sleeve overlays the membrane and a wire bus transmits the signals to a terminal connector. The catheter may include a vented air gap, a multiplexing wire bus, and an internal cable to maintain tension.

Abstract: A novel capacitive proximity tactile sensor is formed by an electrode layer and a compressible non-conductive layer. Positioning a conductive object in contact with the sensor and applying contact force onto the sensor surface allows for both detecting the location of touch (as in traditional proximity sensors) as well as measuring contact force (as in tactile array sensors) due to a capacitance-measuring sensor formed between the electrode layer and the object with the compressible non-conductive layer therebetween. Useful applications of the sensor include input device for consumer electronic item, flexible and thin weight scale, shoe insole for monitoring pressure distribution of a foot while walking, pressure-monitoring seat cushion and others.

Abstract: A removable holder for a smart phone is provided to support the smart phone in front of a driver on a steering wheel. Close proximity of the smart phone allows easy access and good visibility of its display which helps in using the GPS navigation or other features of a smart phone while the vehicle is in motion. Retention of the smart phone assures its steady position when the steering wheel is turned but at the same time allows for its deflection out of the way in case of an airbag deployment. The attachment element of the holder includes two raised bars and an elastic band to form a 3-point contact area with the steering wheel. The smart phone retainer is length-adjustable to accommodate a variety of smart phones. The holder can be easily mounted and removed from the steering wheel without using hand tools.
